5.
Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting tool may contact hidden
wiring or its own cord.
Contact with a "live" wire
will also make exposed metal parts of the power
tool "live" and could give the operator an electric
shock.
6.
When ripping, always use a rip fence or
straight edge guide.
This improves the accuracy
of cut and reduces the chance of blade binding.
7.
Always use blades with correct size and shape
(diamond versus round) of arbour holes.
Blades that do not match the mounting hardware
of the saw will run eccentrically, causing loss of
control.
8.
Never use damaged or incorrect blade
washers or bolt.
The blade washers and bolt
were specially designed for your saw, for optimum
performance and safety of operation.

Kickback causes and related warnings
−
kickback is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an
uncontrolled saw to lift up and out of the
workpiece toward the operator;
−
when the blade is pinched or bound tightly by
the kerf closing down, the blade stalls and the
motor reaction drives the unit rapidly back
toward the operator;
−
if the blade becomes twisted or misaligned in
the cut, the teeth at the back edge of the
blade can dig into the top surface of the wood
causing the blade to climb out of the kerf and
jump back toward the operator.
Kickback is the result of saw misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below.
•
Maintain a firm grip with both hands on the
saw and position your arms to resist
kickback forces. Position your body to
either side of the blade, but not in line with
the blade.
Kickback could cause the saw to
jump backwards, but kickback forces can be
controlled by the operator, if proper
precautions are taken.
•
When blade is binding, or when interrupting
a cut for any reason, release the trigger and
hold the saw motionless in the material until
the blade comes to a complete stop. Never
attempt to remove the saw from the work or
pull the saw backward while the blade is in
motion or kickback may occur.
Investigate
and take corrective actions to eliminate the
cause of blade binding.
•
When restarting a saw in the workpiece,
centre the saw blade in the kerf and check
that saw teeth are not engaged into the
material.
If saw blade is binding, it may walk
up or kickback from the workpiece as the saw
is restarted.
•
Support large panels to minimise the risk
of blade pinching and kickback.
Large
panels tend to sag under their own weight.
Supports must be placed under the panel on
both sides, near the line of cut and near the
edge of the panel.
To avoid kickback, do support
board or panel near the cut.
000154
Do not support board or
panel away from the cut.

•
Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive friction,
